About Pat Pending

Goeie dag! I'm PatP = a tinkerer with a head full of brain-babies and hair full of hurricanes! Why play plain chess when tiny inventors on a board can make move-magic? Every blunder is another step to success! #Innovation 💡

Pat Pending, known as PatP, is a 58-year-old inventor from South Africa with an estimated rating of 1662, which places the bot at the intermediate club level. The character is portrayed as a sprightly, eternally optimistic explorer with unruly hair who starts each day on a new invention, and that curiosity carries over to the board. At this rating PatP has a solid opening repertoire, can calculate two or three moves deep, and shows decent endgame technique, though it does not play with master-level precision. Its most frequent choices as White are the Open Sicilian (173 games) and the Italian Game (165 games), while it answers with the Slav as Black (83 games). A Classical Caro-Kann setup as White appears less often, with 25 games on file. PatP's lucky charm is an old pocket watch, and its favorite quote credits invention as the spark of life. Anyone sitting down against PatP can expect a tidy, theory-aware game with occasional creative detours and endgames that reward patience.

How PatP plays

PatP plays a balanced game with small leanings. It is slightly more defensive than aggressive and mildly prefers trading pieces to holding tension, yet it accepts moderately sharp positions and follows mainline theory more often than offbeat ideas. Typical White games run through the Sicilian Defense: Open or the Italian Game, where central play leads to open positions. Calculation reaches roughly two or three moves, so deeper tactics can slip by.

Who should play PatP

Players rated roughly 1450 to 1900 will get the most from PatP, whose estimated rating is 1662. The bot's mild lean toward solid, mainline play suits improvers who want to practice converting small advantages, handling open Sicilian structures, and finishing endgames. Aggressive attackers can test whether their tactics hold up against a slightly defensive opponent that trades pieces when given the chance. Beginners may find the opening theory demanding.
