Testing Strength Reduction Parameters

I played an entertaining game against MadChess a few evenings ago. Prior to the game, I adjusted MadChess’ strength reduction parameters because I felt their values caused the engine to play too strongly for a given Elo rating. Perhaps my adjustments made the engine too weak. I’m using “feel”, a very unscientific process. Nevertheless, I enjoyed the game. I played white. MadChess played black, set to 900 Elo. Time control is blitz, 5m + 5s. The game began 1.e4 c5 2.Nf3 g6 3.d4 d6 4.dxc5 Qa5+ 5.Nc3 Qxc5 6.Nd5 Qc6. Here I missed a tactic. Can you spot it? I… Continue Reading

MadChess Blunders… Er, Wait

I had a Frankenstein moment yesterday. I use the word “Frankenstein” in reference to MadChess. Meaning, I’ve used my powers of concentration to create this thing, a chess engine, by imagining, thinking, then writing code to “teach” it to play a game of chess. This thing becomes terribly powerful. It’s capable of playing the game I “taught” it with the strength of a super Grandmaster, far exceeding my abilities. While I’m glad I can use MadChess to analyze my games against Internet opponents (after the game is complete, of course), and rely on MadChess’ suggested improvements and variations (it is… Continue Reading
