Tempest Zagreb Ultimate Tournament Chess Set Review: One Bag, Full Kit

3.75 inches. That's the king height on the Tempest Zagreb Ultimate Tournament Chess Set, and that one number tells you this is a club-and-tournament kit, not a coffee table ornament. On paper it's the most complete Zagreb bundle I've seen in a single listing: board, pieces, bag, storage box, scorebook and a hybrid clock. I'd buy it for a player who wants one bag to grab on the way out the door. I'd hesitate if I already owned a clock I trust.

What it is and who it's for

Tempest has built this around a full-size 19-inch board with 2.25-inch squares, a maple and walnut playfield and a solid walnut frame. Solid, not veneer. The board splits down the middle (they call it MagSplit) and joins without a hinge and, according to the listing, without a gap. The 3.75-inch Zagreb pieces are described as extra-heavy and double-weighted, which usually means weight in the base plus a second weight up the shank.

Then there's the rest of the box. A weatherproof messenger-style bag with compartments for board, pieces, scorebook and accessories. A black lacquer storage box with drawstring pouches. A 100-page hardbound scorebook on 150g opaque paper. And the Tempest Deluxe Hybrid clock in walnut and leather, with app integration and game modes that cover chess, Go and backgammon.

That's six seperate items in one purchase: board, pieces, bag, box, scorebook, clock. Board on the table, clock at the side, scorebook open, bag under the chair. If you're weighing this against my picks for the best tournament chess sets, you're comparing a bundle to a build-your-own approach. The bundle wins on convenience and loses on choice.

What the specs actually tell you

US Chess guidance puts king height between 3.375 and 4.5 inches and squares between 2 and 2.5 inches. This set sits inside both at 3.75 and 2.25. The other half of that guidance is the bit people forget: king base should run about 75 to 80 percent of the square. At 2.25 inches, that means a base somewhere around 1.69 to 1.8 inches. The listing doesn't publish a base diameter, so I can't check it for you. Ask before you buy. A heavy piece on a small base wobbles, and an oversized base crowds the square.

Weight is the other silence. "Extra-heavy, double-weighted" is a description, not a figure, and total kit weight isn't listed either. Double-weighted pieces at a 3.75-inch king height should sit planted at blitz pace, and a single-weighted 3.75-inch plastic king feels like a toy next to them. But that's my expectation, not a measurement from this box.

Two specs I do like. The 150g paper in the scorebook is real double-sided thickness, which matters when you're writing 40 moves on both faces of a sheet in ink. And 2.25-inch squares on a 19-inch board is the size most club players already play on, so this board and your old roll-up are interchangeable on a cramped table. More on how that compares across the market is in my guide to chess sets.

What owners report

I'll be straight with you: I haven't played on this set, and the listing I worked from carries no star rating and no review count. So there's no owner average for me to hand you, and I won't invent one. What I can do is tell you what comes up repeatedly with Zagreb-pattern pieces and split boards, and which of those complaints this kit seems to answer.

On Zagreb pieces, owners talk about two things: the weight and the knight. The pattern comes out of 1950s Croatia, and the knight leans forward with a cut mane, which is why people pick it over a standard Staunton silhouette. At 3.75 inches the pieces are big enough that the carving actually reads from across the table. The recurring gripe is the bishop. Thin mitre finials are the first thing to chip, and a bag is where it happens unless the pieces ride in pouches. Tempest includes drawstring pouches and a compartmented bag, which is the right answer to that problem.

On split boards, the standard complaint with cheap ones is the seam. A gap you can feel through a pawn's base will annoyed you by move 30. MagSplit is sold on closing flat with no hinge, and a hinge-free join is the design that actually achieves it. The biggest question mark I'd raise here isn't wood at all. An app-integrated clock makes your phone part of your tournament kit, and a dead phone is a dead clock.

Pros and cons

Pros

• 3.75-inch double-weighted pieces matched to 2.25-inch squares, both inside US Chess guidance.
• Solid walnut frame on the board, not veneer, at full 19-inch size.
• Hinge-free MagSplit join that the listing says closes with no gap.
• 100-page scorebook on 150g paper, which holds up to ink on both sides.
• Bag has separate compartments for board, pieces, scorebook and accessories.

Cons

• No star rating or review count published on the listing as I write this.
• Piece base diameter and total kit weight are not listed, so two key numbers are missing.
• Clock runs through Tempest's app, so your phone becomes a single point of failure.
• No option shown to buy the pieces or the board on their own.
• You may be paying again for a clock you already own.

Specs at a glance

Alternatives worth a look

The product data I was given lists this one bundle and nothing else, so I'm not going to invent rivals to fill space. Here are the three directions that make sense instead.

If you want the traditional club look and a silhouette every opponent recognizes, a standard Staunton set at the same king height is the safer buy, and the best Staunton chess sets covers the range from budget boxwood to proper weighted pieces. You lose the carved knight. You gain a pattern that never looks out of place.

If the board is going to be the centerpiece and you want the top of the market, the House of Staunton review walks through what the money actually buys at that level. That's a different purchase with a different purpose. Expect to pay for wood grading and hand finishing rather than for a bag and a clock.

If this set is going to live on a side table and get looked at as much as played, a display set is the honest answer. Anything above the 4.5-inch king ceiling in the US Chess guidance isn't a tournament set anymore. My picks for the best luxury chess sets sit in that territory.

Should you buy it

Yes, if you're a club or tournament player who wants one matched kit and doesn't want to assemble it piece by piece. The 3.75-inch king on 2.25-inch squares is the right size, the solid walnut frame is the right material for something that travels, and the hinge-free split is the right design. Six items for one decision is a fair trade.

Two things to check first. Ask the seller for the piece base diameter, because the listing doesn't give it and the 75 to 80 percent rule is what keeps heavy pieces from wobbling. And decide if you're happy running a clock through a phone app, since that's the one part of this bundle you can't swap out if it annoys you. If you'd rather keep the board and choose your own timing, the best modern chess sets have plenty of split-board options. But as a single purchase for a player who shows up, sets up and plays, this is the one I'd put in the bag.
