English orangutan

The English Orangutan arises after 1.c4 Nf6 2.b4. ECO code: A15.

Overview

This unusual line combines the English Opening with the queenside pawn advance characteristic of the Polish Opening. White aims for Bb2 with long-diagonal pressure while maintaining the c4-pawn's influence on d5.

Strategic Themes & Plans

The b4-pawn can become a target, but it supports queenside expansion and enables a rapid Bb2. Black should respond with central play—2...e5 or 2...d5—to exploit White's neglect of the centre. The opening is rarely seen at the highest levels.
