Don't be greedy: the Blackburne Shilling

The setup: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4?! — a strange move that leaves e5 hanging on purpose. The trap: 4.Nxe5? Qg5! hits the knight and g2 at once. If White grabs more with 5.Nxf7??, then 5…Qxg2 6.Rf1 Qxe4+ 7.Be2 Nf3# is mate. How to avoid it as White: don't take on e5. Simply 4.Nxd4 exd4 5.c3 or 4.O-O gives White a comfortable game — the trap only works on greed.

A chess trainer that remembers what you missed

Most games between club players are decided by a short tactic — a fork you didn't see, a pin you walked into, a back rank you forgot to air out. Endgame closes the loop: learn the pattern on the Path, use it against a bot, get graded, and drill the miss until it sticks.
