Home * Engines * Natwarlal

a Chess Engine Communication Protocol compliant open source chess engine written by Pallav Nawani in C++. Natwarlal played the CCT9 with respectable 4/7. The name of the engine was inspired by Mithilesh Kumar Srivastava, better known as Natwarlal, a Indian con man [1] known for having repeatedly "sold" the Taj Mahal, the Red Fort, and the Rashtrapati Bhavan and also the Parliament House of India along with its 545 sitting members. He was a living-legend in his lifetime and a legend even after his death [2].
Natwarlal [3]


Natwarlal uses a 0x88 board array along with piece-lists to represent the board. It features a negamax alpha-beta PVS with various extensions, reductions, null move and futility pruning, and double transposition tables inside an iterative deepening framework with aspiration windows. The evaluation considers pawn structure and king safety [4].
